This study was performed to investigate the relationships between obese index and major risk factors of cardiovascular disease in CVD patients. Anthropometry, food intake patterns, blood pressure, serum lipids and hematological values were analyzed in 550 patients from June, 1991 to August, 1992. The results are as follows: Total food intakes, especially total vegetable food and alcohol intakes were significantly related with obese index, so that the heavier patients tended to consume more carbohydrate and less fat. The blood pressure were observed to have positive correlation with obese index in man but not in women. However, both in men and women, blood levels of TG, TC, and VLDL tended to be related to obese index positively, while HDL and HDL-C were shown to be oppositive. So, it seems that as the degree of obesity is higher the blood pressure and blood lipids patterns worse. Therefore, these results suggest that obesity is one of the major risk factors of CVD, and for prevention & treatment of the disease, controlling body weight by nutritionally adequate diet along with alcohol restriction is necessary.

This paper proposes a user interface for enhancing immersiveness and usability by combining hologram and haptic device with common Leap Motion. While Leap Motion delivers physical motion of user hand to control virtual environment, it is limited to handle virtual hands on screen and interact with virtual environment in one way. In our system, hologram is coupled with Leap Motion to improve user immersiveness by arranging real and virtual hands in the same place. Moreover, we provide a interaction prototype of sense by designing a haptic device to convey touch sense in virtual environment to user's hand.

With the increasing elderly population in Korea, dementia has become a mojor health problem in Korea. Several studies have been conducted on the association between dementia and dietary intake, especially vitamin E and vitamin C. The purpose of this study was to investigate the effect of vitamin E and vitamin C supplementation on the decrease in cognitive function induced by scopolamine(300mg/kg) in rats. Rats were divided into three groups : control, vitamin C, and vitamin E supplementation(2.4g Vit C or Vit E /100g diet) and fed the diets for 6 weeks. There were significant decreases in active avoidance response and brain acetylcholinesterase activity in the control group, but no significant differences were observed in the vitamin E and C groups after scopolamine treatment. Brain dopamine concentration of vitamin E and C groups was significantly higher than those of control group after scopolamine injection. The concentrations of brain norepinephrine also showed similar tendence, even though it was not statistically significant. These results indicate that vitamin E and vitamin C may protect against the cognitive function decrease induced by scopolamine. However, it is still unclear how vitamin E and C influence brain neurotransmitters and improve cognitive function. Further study is need to elucidate the role of vitamin E and C supplementation in the prevention of dementia.

The theory of psychotherapy was established by a single case study. Even though it was lack of generality, it must have been a basic important role in the clinical field. Under the above assumption, the therapist had only one client as a case study that couldn't be well adjusted and had many conflicts because he not only had many complexes, but could'nt recognize complexes themselves. The chief problems to the client who complained the psychosomatic symptoms and anxieties were assumed dependency and inferiority complex. In order to recognize these complexes, therapist had 30 interview section with him. The major goal of therapy was the maturation by which the ability of recognition of complex was obtained. The measurement of effect as to whether the client was matured or not was the advancement of schoolwork result and the progress of sociometric rating. Besides, the therapist exerted all the possible effort in interpreting psycological problems was found in every section of interview. The result of this therapy was known as a full progress in academic credits and in the development of human relationship as same as therapist's expectation. In this study, the therapist used the psychoanalytic insight therapy and the client-centered therapy as the therapeutic method for the client.

Purpose: The purpose of this study was to compare the effects of oral hygiene with 0.1% chlorhexidine or with normal saline on the incidence of pathogens in the oral cavity of patients in Intensive Care Units (ICU). Method: A quasi experimental design with non-equivalent control group and non-synchronized design was used. For the study 46 patients were recruited from a university hospital (24 for the experimental group, 22 for the control group). patients in the experimental group received mouth care with 0.1% chlorhexidine gluconate and those in the control group received mouth care with normal saline twice a day for 7 days in a row. Oral samples were taken for bacterial cultures on admission day, the 4th day and the 7th day for both groups. Results: The incidence of oral pathogens decreased in the experimental group, and increased in the control group. There was no significant difference in the incidence of oral pathogens between the two groups. However oral hygiene using 0.1% chlorhexidine gluconate decreased the incidence of oral pathogens significantly for patients who already had pathogenic bacteria in their mouths on the admission day. Conclusion: The results suggest that mouth care with 0.1% chlorhexidine is effective for decreasing the incidence of oral infection for ICU patients who have oral infections.

이 연구의 목적은 유산균(LAB)의 항스트레스 효과를 알아보기 위함이다. 본 실험에서는 ICR 마우스에게 구속 스트레스를 가하면서 혼합유산균과 홍삼추출물을 경구투여 하였다. 5일간 Normal 그룹을 제외한 saline (control), LAB100, LAB200, RGE200에게 구속 스트레스를 주었다. 구속 스트레스를 가한 후에 ICR 마우스에게 kg당 100 mg ($3.0\times10^{11}$ CFU/g) 또는 200 mg $3.0\times10^{11}$ CFU/g)의 혼합유산균(Lactobacillus acidophilus, Pediococcus pentosaseus, Bifidobacterium longum SPM1205)을 투여하였으며 대조물질로는 홍삼 추출물(Red ginseng extract) 200 mg (홍삼추출물)/kg (마우스)을 투여하였다. 마지막 실험일에는 locomotor와 elevated plus-maze 실험을 통하여 마우스의 행동변화를 측정하였다. 그 결과, 혼합유산균을 투여한 그룹에서는 스트레스를 일부 억제하는 효과를 보였다. 특히 Elevated plus-maze 실험에서, 스트레스를 받은 마우스는 open zone에서보다 closed zone에서 더욱 많은 시간을 보냈다. 그렇지만 혼합유산균을 투여한 그룹에서는 open zone에서 더욱 오래 시간을 보냈으며 그 시간은 saline과 RGE200 그룹에 비해서도 길었다. 그것은 또한 아무것도 처리하지 않은 Normal 그룹과도 비슷한 결과이다. 그리고 마우스의 분변에서 유산균수를 측정하였는데 스트레스를 가하고 혼합유산균은 투여하지 않은 saline 그룹에서는 유산균수가 감소했지만 혼합유산균을 투여한 LAB100, LAB200 그룹에서는 유산균수가 증가하였다.

The relationship between cognitive function and dietary patterns in Korean elderly women was investigated in this study. Twenty-four-hour dietary recall and cognitive function tests were performed in 170 elderly women aged over 60 years. Average age of the subjects was 71 years and the average number of family members was 3.3. Most of the subjects had less than seven years of education and their monthly income was much lower than the Korean average. Most of the subjects engaged in regular exercise and did not indulge in drinking and smoking. The average cognitive function score of the subjects was 58.4. Most of the subjects appeared to consume insufficient amount of food ; average intakes of energy, Ca, iron, vitamin A, and riboflavin were lower than RDA for the elderly. Cognitive function score was positively related to education level and regularity of exercise. Also, cognitive function score had a strong relationship with food intake such as total amounts of foods, fish and shellfish, milk and dairy products, total animal food, fruit, bread and sugar. Energy, protein, Ca, p, riboflavin, and niacin were also shown to have positive relationships to cognitive function score, while carbohydrate caloric ratio had a negative relationship with cognitive function. According to the results of multiple regression analysis, factors that most influenced on cognitive function were education level and riboflavin intake. The subjects who had more than seven years of education had significantly higher cognitive function scores than those with no school education. And cognitive function scores f3r those who consumed more than 2/3 of the RDA for most nutrients were significantly higher than the ones fir the subjects who consumed less than 2/3 of the RDA. These results suggest that proper education and adequate nutrient intake in quantity and quality by achieving food diversity are essential in maintaining cognitive function in later life (Korean J Nutrition 31(9) : 1457-1467, 1998)

The proposed cooperative 3D modelling system enables more efficient modeling works by improving current cooperation systems. Current 3D modeling tasks work on off-line and most of works are cooperation systems which communicate by files. These cooperation system cannot be interactive, occurs time delay while feedback and must have some programs which can read the files. This paper solves these problems using web that has the characteristics of network and proposes new cooperation system form. Using WebGL(Web Graphics Library) which is proposing technology in technical realization of Web 3D modeling, we make 3D objects in web browser and these objects can be manipulated by server-client communication. Therefore, if people use this system, they can use real time interaction and feedback. Also this system lowers a software installation necessity and can access everytime if web browser is installed.

Community-acquired antimicrobial resistant bacteria are an emerging problem whole world-wide. Generally, Hands are main mediator of pathogen transmission as compared with other body parts. So, the purpose of this research was to investigate the microbiological quality and antimicrobial susceptibilities of samples which were collected from the door knob and surface in public- and home-facilities, and also hand. Of total 191 samples, 71 samples (37%) were shown to be of high-level total bacterial count (>$10^8\;CFU/cm^2$). And presence of Staphylococcus and Enteric bacilli was observed in 61 samples (32%) and 76 samples (40%), respectively. Antimicrobial susceptibilities of staphylococcal isolates from the samples were tested for six different antimicrobial agents, which are in wide spread clinical use in Korea, as well as four new antimicrobials, daptomycin, linezolid, quinupristin/dalfopristin and tigecycline. Among staphylococcal isolates, antimicrobial resistance were observed in oxacillin (n=6), mupirocin (n=7), vancomycin (n=1), quinupristin/dalfopristin (n=2) and gentamicin (n=5). Fortunately, all the isolates were susceptible to new antimicrobial such as daptomycin, linezolid and tigecycline. Furthermore 4 Enterococcus faecalis were isolated from four hand samples, and all these isolates exhibited multidrug resistance to four different antimicrobial (oxacillin, quinupristin/dalfopristin, mupirocin, gentamicin). Also, 5 Escherichia coli were isolated from surface in home (n=3), door knob in public facilities (n=1) and hand (n=1). Escherichia coli isolated from hand was high-level resistant to tigecycline ($128{\mu}g$/ml) and gentamicin ($64{\mu}g$/ml).
